Discussion
After some active and warm weather, dry and quiet conditions will
commence for the majority of the forecast period. Temperatures will
cool off noticeably, as temps come in just below normal through the
end of the week and into the weekend. Upper level troughing will
continue to hang around today as surface ridging begins to slowly
build in. This will allow for a continuation of cold air advection
with northwesterly flow. With troughing and some low level moisture
still in place over the area, there will some strato CU development
during the afternoon. There may be some potential for a brief
sprinkle during the afternoon hours, but that is about it.

Temperatures at 850mb drop into the single digits before cooling off
a little more on Thursday. This extra little cool down will come as
a shortwave moves down across the area bringing a chance for some
shower activity to the thumb area during the day on Thursday. More
expansive high pressure and upper level ridging build back behind
the quickly exiting shortwave bringing dry conditions all the way
into the weekend. Changes to the quiet conditions do not come back
into play until into next week.

Marine
Moderate northwest wind will continue over marine areas early today
before easing slightly by late afternoon and evening. Gusts to
around 30 knots will be common over the open waters of lake huron
where the long fetch will build the highest waves toward the
canadian border. Wind speed will diminish tonight while a secondary
front trough reinforces cool air over the warm lake water through
Thursday. This will be a favorable condition for waterspouts,
especially where any land breeze development is possible. High
pressure settling overhead by Friday will bring in enough dry air to
inhibit cloud formation and produce favorable wind and wave
conditions through the weekend.

mostly clear skies and light winds expected to hold for the rest of
the night, but continued cold advection and steepening low level
lapse rates post sunrise expected to allow for a goodVFR (possible
brief MVFR in late morning) CU up in clouds spreading from north to
south, with even isolated showers popping up during the afternoon,
mainly over the thumb region. Westerly winds increasing to around 15
knots by afternoon with diurnal mixing.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
